Dynamic Workers are now in Open Beta, all paid Workers users have access. Secure sandboxes that start ~100x faster than a container and use 1/10 the memory, so you can start one up on-demand to handle one AI chat message and then throw it away. Agents should interact with the

Jesus Christ @zoom_us, you've apparently let a whole school in Chile sign up for a paid account using my e-mail address, because you never verified it. I went to create my own account, it said I had one, so I "forgot password", and now I own this school's admin account.

Reminder that Judge William Haskell Alsup, who first heard Oracle v. Google, actually LEARNED JAVA in order to make an informed ruling, while these higher-court jokers are relying on analogies to Harry Potter and grocery stores.

Wow. This SanDisk SSD model fails at 40,000 hours exactly. Primary and backup servers each had RAID-1 and they all failed at the same time. When setting up a RAID-1 mirror, always try to pair two SSDs from entirely different chipset makers.

My husband correctly guessed what caused today's Hacker News failure. He'd experienced it before. news.ycombinator.com/item?id=320285…

Oh come on, how hard could it be to keep these links working forever? It could be like a 5-line Worker backed by KV and you'd never have to touch it once deployed.
Google’s shortened goo.gl links will stop working next month

Yeah I don't actually think they were trying to get around the ban, I just think the timing is funny.

TIL Swedish time format is exactly the ideal time format, that is, "YYYY-MM-DD HH:MM:SS". In JavaScript, you can do `date.toLocaleString("sv")` to format this way. I wonder if it's safe to assume this will never change...

Those benchmarks from @theo revealed some interesting issues in Workers. Happy to say it's all fixed now, save for some lingering next.js-specific stuff we're continuing to work on. Thanks for the reproducible test cases, @theo. (Link to blog post in reply.)

Folks, I did it again. I made another RPC system. I know, it's a problem. But bear with me! I think this is the best possible JavaScript RPC. It has all the power of Cap'n Proto with no need to write schemas. There is almost no boilerplate at all.
We've added JavaScript-native RPC to Cloudflare Workers

The problem is that my e-mail address is temporal at gmail. It was my teenage gamer tag. I need to change it. But it turns out "temporal" means "temporary" in Spanish. So Spanish-speaking people all over use it as a placeholder address!
